FURTHER PROPAGATION INVESTIGATION OF A LOW DENSITY URBAN ENVIRONMENT WITH DRAINS

In South East Asian countries, particularly in a developed Asian city, open-trench drains systems are prominent due to climatic differences. Open-trench drain structures occupy a great part of the terrain topography in Malaysia, and therefore this project aims to further investigate the impacts that open-trench drain systems have on radio propagation prediction in a low density urban environment. Towards that end, we have engaged an interactive 3D ray-tracing tool to build the environment depicting a low density setting with clusters of low rise building structures oriented far apart from each other. The existence of open-trench drains is incorporated into a mock city model to obtain propagation prediction results for different operating frequencies. One of the primary differences this study in comparison to the existing studies on ray-tracing modeling of an urban city with open-trench drains is that the quantity of building models and open-trench drain structures are generated over a wider area to mimic actual low density city settings. When such scenarios are considered, the impacts of open-trench drain structures fade away.
